Adolescent childbirth, miscarriage, and abortion: associations with changes in alcohol, marijuana, and cigarette use.
Article in Journal of child psychology and psychiatry, and allied disciplines, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdolescent girls who become pregnant demonstrate greater risk for substance use than same-aged peers. However, it remains unclear how risk relates to normative changes in adolescence. Few studies have examined adolescent substance use changes before, during, and after pregnancy and considered how pregnancy outcomes (childbirth, miscarriage, abortion) differentially influence substance use changes. The present study examined associations between different adolescent pregnancy outcomes and within-person changes in substance use from prepregnancy to postpregnancy.
methodsParticipants included 2,450 girls (52% Black) oversampled from low-income urban neighborhoods in Pittsburgh, PA. Participants self-reported pregnancy outcomes and substance use frequency (alcohol, cigarette, marijuana) annually from ages 11-20. Fixed effects regressions focused on first births, first miscarriages, and first abortions occurring from ages 12-19 to test the associations between pregnancy outcomes and within-individual changes in substance use from prepregnancy to postpregnancy. By design, models controlled for all potential time-stable confounds, and models included age and subsequent pregnancies as time-varying covariates.
resultsConsistent with prior studies, girls who became pregnant (20%) reported greater early risk for substance use problems than never-pregnant adolescents, including earlier age of onset and more regular marijuana and cigarette use. Childbirth predicted a 26%-51% within-individual reduction in alcohol, marijuana, and cigarette use that remained significantly lower than prepregnancy levels after childbirth. Alcohol and marijuana use decreased (32%-47%) after miscarriage. Abortion was not associated with long-term changes in substance use; however, marijuana and cigarette use gradually increased (44%-46%) in the years leading up to the year of and after abortion, respectively, before returning to prepregnancy levels.
conclusionsFindings highlight important differences in adolescent substance use patterns based on pregnancy outcome. For pregnant adolescents with heightened pre-existing risk for substance use, pregnancy may be a window of opportunity for substance use screening and behavioral intervention.
